use existing vm_search_method()

Browse Source 
Ko1 plans to implement Guild.  That can interface the caching
mechanism introduced here.  To prevent future breakage we would
better avoid rolling our own code here.  Instead use the existing
vm_search_method() which would be modified by him.

This commit deletes some asserions, but they are in fact checked
inside of vm_search_method().
